Ok, I'm doing my Control Panel design right now, and I need to know the size of the plastic ring of the super joystick( I think its call the bezel, not sure im not english

)
I can't mesure it myself.. I ordered my joystick yesterday

I looked on the happ's site, figured out that pushbuton bezel was 1.30 inch so its ok, but the super joystick doesnt describe it..
thx
